About the Project

We invite applications for a fully-funded PhD position that aims to push the boundaries of oral health research. This project focuses on investigating the effectiveness of a commonly used oral care ingredient on oral biofilms, with the objective of providing a comprehensive understanding of the mechanisms of action of sodium bicarbonate.

Oral biofilms play a critical role in oral health, being associated with various oral diseases such as dental caries and periodontal disease. By exploring the mechanisms of action of sodium bicarbonate, this project seeks to uncover the potential benefits of utilizing this ingredient as a preventive measure against biofilm formation on oral surfaces. The project takes an interdisciplinary approach, harnessing cutting-edge techniques from the fields of microbiology, material science, and biomolecular characterization. By integrating expertise from diverse disciplines, this project has the potential to drive innovation and foster knowledge exchange in the field of oral health.

This exciting collaboration brings together a cross-disciplinary team from the Faculty of Sciences and the Faculty of Medicine & Health Sciences at the University of Nottingham1,2 and Haleon3, a world-leading consumer health company renowned for its global oral care brands, including Sensodyne and Corsodyl.

If you are a motivated and passionate individual with a background in microbiology, material science, or related fields, and are eager to make a significant contribution to the field of oral health research, we encourage you to apply. PhD candidates joining this project will benefit from state-of-the-art research facilities, such as Biofluidic Microscopy and 3D OrbiSIMS mass spectrometry, expert supervision, and the opportunity to engage with industry partners to translate their research findings into real-world impact.
